An Econometric Method for Estimating Population Parameters from Non-Random Samples: An Application to Clinical Case Finding

The problem of sample selection complicates the process of drawing inference about populations. Selective sampling arises in many real world situations when agents such as doctors and customs officials search for targets with high values of a characteristic. We propose a new method for estimating population characteristics from these types of selected samples. We develop a model that captures key features of the agent's sampling decision.

Demand-side determinants of access to healthcare service: Empirical evidence from Africa

This study identifies the key determinants of access to healthcare in Africa and estimates the short-run and long-run effects of these determinants. Panel data from 37 African countries, collected from the World Bank Development Indicators and World Health Organisation databases for the period 1995-2012, were analysed using the pooled mean group estimators. Income appeared the strongest determinant of access in the long run in countries in Africa included in the sample. Access to healthcare was a necessity with the long-run income elasticity for access to healthcare being 0.1149.

The impact of health on the employment and earnings of young South Africans

This paper estimates the impact of health on employment and earnings among individuals aged 15-39 years in South Africa.  Though one of the richest countries in Africa, South Africa is plagued by substantial disease burden especially from communicable diseases, injuries, maternal and child mortality, and non-communicable diseases. The country also has very high unemployment rates, with the unemployment rate among those aged 15-24 years exceeding 50% in 2014 (according to the International Labour Organization definition).

Impact on Health on Labour Force Participation in South Africa

This paper quantifies the impact of health on labour force participation, using South Africa as a case study. This is important given the essential role the labour market plays in economic growth and the potential for poor health to adversely affect labour market outcomes. South Africa has experienced significant disease burden especially due to communicable diseases like HIV/AIDS and tuberculosis. Moreover, conditions like obesity remain a public health concern. Furthermore, the country has witnessed declining labour force participation in recent years.

Diagnosing Deep Roots of Development: Genetic, Disease and Environmental Factors

We examine the association between indicators of real GDP per capita and the ACP1 genetic adaptation to disease and ultraviolet radiation environment. We find a strong impact that varies across the A, B, and C alleles. The result is robust to controlling for reversal of fortunes, migration, and potential endogeneity of the genetic adaptation.

Effects of Social Norms on Multiple Partnerships: Evidence from Young Adults in the Metropolitan Communities of Cape Town, South Africa

Even though antiretroviral treatment is becoming more efficient and available, new HIV infections still occur. This is particularly the case in sub-Saharan Africa. Sexual transmission of HIV is still the main mode of transmission in sub-Saharan Africa, and multiple sex partners have been shown to be crucial for the spread of the epidemic. It is therefore problematic that sexual risk-taking, in terms of multiple sex partners, persists in spite of HIV awareness and knowledge.

‘Know Your Epidemic’: The Effects of Expected Health and Contextual Health Uncertainty on Risky Sex

This study measures the link between expected health and contextual health uncertainty on sexual behaviours associated with the risk of HIV infection. We extend similar studies on the subject by focusing on contextual factors as a way of explaining individual sexual behaviour in low and high HIV infection areas across sub-Saharan Africa. Overall, we find expected health and contextual health uncertainty to have significant effects on sexual risk taking. These results point to the fact that context is equally important than the widely held view that individual level characteristics (e.g.

Does Famine Matter For Aggregate Adolescent Human Capital Acquisition In Sub-Saharan Africa?

To the extent that in utero and childhood malnutrition negatively affects later stage mental and physical health, it can possibly constrain later stage human capital acquisition, which is an important driver of economic growth. This paper considers the impact of famine on aggregate adolescent human capital formation in Sub-Saharan Africa. We parameterize a joint adolescent human capital and food nutrition production function to estimate the effects of famine on primary school completion rates of individuals age 15 - 19.
